    I don't know, but also thinking seriously to go step back to 2.0 for now or until some issues are resolved.

    Yeah I do love the fact that the browser has yet to crash on me finally, but i miss the predictive text with the blackberry bridge that I use quite a lot. More than the actual browser itself.

    That's a Bridge problem (which RIM has acknowledged that it has a bug and requires an update), not the Playbook OS 2.0.1 problem.

    Anyway....someone knows how to revert to version 2.0?

    Cause some android apps dont work after upgrade....so for me there are more negatives than positives on the new 2.0.1.

    I shouldn't have updated and like everyone here I have my reasons. Next time I'm gonna wait at least 2 weeks before I update.

    Irsan, thanks for this. I have never rooted my PlayBook and very cautious to do so. Do you know of any problems you might have after you downgrade? Any malfunctions or anything?

    This isn't related to rooting.
    If you choose Full OS for downgrade, there will be absolutely no problems. It is exactly the same as if you just updated to 7971. It's same method RIM uses for updates.
    CoreOS should be fine too but the in-built apps will be 1.358 still.

    Thank you very much Xsacha. I didn't read through the instructions ; I just saw DingleBerry, and immediately thought I was going to have to root my PB. Another question, since there will be absolutely no problems, a user who downgrades to 0.7971 will still have the option to regularly update to 1.358 if he/she so chooses, right?

    You are always extremely helpful.

    I believe the Android player will go back to the version it was in 0.7971 if you downgrade since it is built in. You shouldn't lose your data. But do a back up... which leads to another question: Is a 1.358 back up compatible with 0.7971?

    They should still be there.

    I have not tried it and maybe as you follow the steps it will be fine but I'm not sure that I understand Steps 3 and 4. Will these custom folders be obvious when running those steps?

    And THANKS for sharing this technique.

    the custom folder is in the firmware folder...this curstom folder must contain your firmware files (not firmware folder)

    No that won't work. It is signed and by modifying the contents in anyway you break the signature. If that would work, it would have been done weeks ago.

    I haven't found any bumps with CoreOS downgrading.

    anyone was able to downgrade the android runtime engine?
    What is the current version of the Android Player on OS 2.0.1.358? What was it in 0.7971?

    In the middle of my downgrade.

    EDIT: I see from a different thread that the android player versions for OS1.358 and OS0.7971 are 2.0.1.30 and 2.0.0.56 respectively

    Android player HAS been updated, you'll notice it is version 2.0.1.30 as opposed to the 2.0.0.56 (I believe, need to double check with my videos) it was before
    I just successfully downgraded to OS 2.0.0.7971 and the android player version is 2.0.1.30 (the same as in OS 2.0.1.358)

    Do you mean downgrade to a rootable OS and have root access so as to extract the Android Player?
